Title: Apparatus for detecting and recording corona discharge in a moving insulated power cable having a semiconducting insulation shield
IPC: G01R31/02
Filed: 1967-09-20
Abstract: An apparatus for testing a cable having a semiconductor insulating shield is of the type where the cable is passed through an elongate liquid bath along which potential gradients are maintained by having earthed electrodes in contact with the liquid at the ends of the bath and a high voltage electrode at the centre. Capacitive pick-ups coupled to the cable enable the occurrence of corona to be detected. To prevent overheating caused by longitudinal current flowing through the semiconductor shield of the cable, the high voltage is repetitively applied to the centre electrode for relatively short time intervals only (about 2 cycles of mains frequency) and relatively long intervals (about 20 cycles) are left between successive applications. A high voltage at mains frequency is applied to the centre electrode 14 of the bath from a supply 25 via a switch 24 and transformer 23. A tapping on the secondary of the transformer is used to apply relatively high voltage to the capacitive pick-offs 12 and 13, to prevent spurious discharges. The two pick-offs are differentially connected to a transformer 37 and are associated with tuned circuits 31, 32 respectively. By adjusting the circuit 31 in the absence of corona, noise signals are balanced out. However a corona signal effects the two pick-ups differently, and a differential signal is derived from the transformer. This is filtered and amplified and passed to a gate 40, which is opened only after the supply has been switched on at 24, so that the system does not respond to the initial switching transients. The switch 24 and gate 40 are controlled by suitably timed and spaced pulses from a trigger circuit 44. When the gate 40 is opened, any detected signals are passed to an oscilloscope 42 and a recorder 43, synchronized with the cable movement. The apparatus of Fig. 1 detects the occurrence of corona above a pre-set value of voltage (set by the positions of pick-offs 12-13). To measure the corona inception and extinction voltages, the pickoffs are replaced by capacitor stacks extending along the bath on each side of the centre electrode, and the simultaneous outputs from the stacks are each processed by circuitry similar to that shown in Fig. 1 and then divided see Fig.2 (not shown). The amplitude ratio of the two outputs corresponds to the position of the void at which corona occurs.

Patent ES-356024-A1 (ES)
Title: Static punch card reader
IPC: G06K7/06
Filed: 1968-07-11
Abstract: Insertion of a punched card in a slot 5, Fig. 2, releases a pressure plate 40 to urge the card against sensing members 164, Fig. 1B, which pass through holes 130 in an insulating plate 124. Plate 40 may have holes 44 corresponding to holes 130, whereby contact parts on the sensing members 164 make or break contact with conductors 132 on plate 124, or contact pads may be provided on plate 40 for co-operation with the ends of sensing members which pass through card holes. When a card is inserted, its lower edge engages lug 116 to release latch 108, and arms 35, Fig. 2, pivot counterclockwise to rotate cam 31 and urge pressure plate 40 to the left. The fact that plates 124, 40 are not joined allows sensing of cards with different thicknesses, though this is an optional feature. After the initial movement of plate 40 and making of contact between selected sensing members 164 and conductors 132, engagement of arms 35 with pins 74 pivots arms 68 counterclockwise, whereby cam 90 is moved to the right and cam surface 155 of frame 150 (to which plate 124 is attached) rides over first surface 102 and then surface 104. The consequent vertical reciprocation of plate 124 effects a double wiping of the contact parts of members 164 on conductors 132, the final contact positions being on pre-wiped portions of conductors 132. An adjusting screw 86 is provided so that the normal position of cam 90 may be shifted to the right with cam surface 155 engaging surface 104. Operation of the reader then causes surface 155 to travel over surface 104 and the top left-hand surface of cam 90 to effect a first wiping of the contacts, and a second, oppositely directed wiping is caused by deflection of the sensing members in the final movement of plate 40. The reader is reset by clockwise movement of lever 2.

Title: A process for producing {60 -amino acids
IPC: C07C/
Filed: 1968-08-01
Abstract: A process for producing alpha -amino acid by hydrolyzing a hydantoin compound in which the hydrolysis is effected while withdrawing out of the system ammonia and carbon dioxide generated during the hydrolysis and while during the reaction period, adjusting the amount of reaction medium to at least 1.5 l. per mole of the hydantoin compound initially employed. Particularly, a process in which the hydrolysis is effected in such a manner that an aqueous alkaline solution of hydantoin compound is fed to the upper part of a plate column-type reactor or packed column-type reactor and, simultaneously, steam is fed from the lower part of said reactor, while withdrawing ammonia and carbon dioxide out of the system. By thus effecting the hydrolysis without concentrating the reaction liquid, and while withdrawing the generated gases out of the system, alpha -amino acid can be produced in high yields.
